Embodiment Construction

[0031] Various embodiments of the invention will now be described in detail, examples of which are illustrated in the accompanying drawings and the description below. While the invention will be described in conjunction with exemplary embodiments, it will be understood that present description is not intended to limit the invention to those exemplary embodiments. On the contrary, the invention is intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims .

[0032] The present invention relates to a technique of automatically calculating the replacement timing of brake friction pads provided in a brake system of a vehicle and notifying the driver of the replacement timing, and based on the fact that a friction pad wear sensing system (ESC) is installed in the vehicle. Trend, by using ESC's ECU control ...

Abstract

Disclosed are system and method for abrasion warning of a brake friction pad of a vehicle. The system may include a friction pad abrasion sensing system (ESC) including a pressure sensor. The ESC system may recognize a speed change in association with a wheel speed sensor of the vehicle, measure a braking pressure using the pressure sensor included in the ESC system when the vehicle is decelerated, calculate and accumulate an abrasion index proportional to the measured braking pressure, and generate and output a notification message when the accumulated abrasion index is more than a predetermined reference value.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2014-21949 filed on February 25, 2014, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a brake pad wear warning system using a pad wear sensing system (ESC), and more particularly, to a technology for automatically detecting a brake system by using an electronic control logic of an ESC system installed in a vehicle The replacement timing of the friction lining and inform the driver of the replacement timing of the friction lining without adding a separate additional device. Background technique [0004] Generally, the friction pads applied to the braking system of automobiles are used to stop the vehicle by friction force, and since the brake pads use friction force every time braking, the brake pads are inevitably subject to wear. Therefore, when the brak...
